你真的搞懂了Arduino的HIGH和LOW吗?多大的电压是高电平HIGH?多小的电压是低电平LOW?耳听为虚眼见为实。直接通过digital Write D2 HIGH和digital Write D4 LOW然后用万用表量一下电压可以看到,输出HIGH是大于4v输出LOW是接近0v再来看看输入的情况这里用一台开关电源
大佬们,萌新问个问题..就是我在做一个小车,然后我想不用拓展板,就用uno板来实现电机的正转与反转,然后我在网上就查到了一个4个开关的电路能实现正反转,所以我想能否用2个引脚的高低电压差来模拟开关的开和闭
例如:boolean output = HIGH;
最近与朋友聊到,我们的REF7306可以高边(high side)与低边(low side),然后朋友问我,啥子叫high side与low side,我…… 一 先看图1 2. 驱动负载有两种基本方法:低边驱动,高边驱动。 电路中,晶体管常常被用来当做开关使用。晶体管用作开关时有两种不同的接线方式:高边(high side)和低边(low side)。高边...

arduino有没有办法让输出管脚悬空(而不是LOW)?arduino里面数字管脚的输出有HIGH和LOW分别对应的高电平和低电平, 有没有办法让输出管脚悬空(而不是LOW)?悬空的意思是可能为高或者可能为低 因此，设置 pinMode(DX, INPUT) 并且外部不接其他上拉或者下拉就是悬空了 那...
